Answer: 46
Step-by-step explanation:
Given : Margin of error : E= 17
Standard deviation : 
Critical value for 90% confidence level :
Formula to find sample size is given by :-

i.e. 

Hence, the required minimum sample size = 46.
Answer:
The method of moment (MOM) estimator as: 


Step-by-step explanation:
From the question, the correct format for the probability density function is:

where θ > 0 is an unknown parameter.
(a) The MOM estimator can be calculated as follows:




suppose E(X) = 
Then;



making
the subject of the formula, we have:



squaring both sides, we have:
The method of moment (MOM) estimator as: 
b) If the observations are 
Then,






Finally, the point estimate of the estimator
is




By the Pythagoras theorem:-
h^2 = x^2 + x^2
(where h = hypotenuse)
h^2 = 2x^2
h = sqrt2 x
